I don't see any reason not to comment about a recording you have of the show, unless you've been sworn to secrecy. You're probably better qualified to discuss the score than many of us, since you've been able to listen to it over and over again, as opposed to just hearing it once during a performance. I gather it hasn't grown on you.
As far as the original question (is it better to get great seats for a show still developing in tryouts or to wait for the finished version to hit Broadway) you have to consider these issues:
Is the ticket price a big financial outlay for you? Will you feel like you wasted a lot of money if the show doesn't seem polished? (This was a common complaint on the Chicago Tribune reader's board.) Can you appreciate great performances in a less than perfect setting? Having seen an early preview of Pirate Queen I can tell you that even though I hated the book and score I felt the incredible cast gave me my money's worth. Are you interested in having some insight into how a show is developed? Since Chicago gets a lot of out of town tryouts I was able to see early versions of Aida and The Producers, which I found fascinating. (Aida was horrible at first!) I would loved to have been able to see the early version of Wicked, even though I've heard it was way too long and had other problems.
